Hi Gilles,
Please try to avoid creating merge-of-master commits like 68bec0ae ("Merge
branch 'master' of..."), they just clutter the history. A rebase is almost
always more appropriate in this situation.
https://github.com/open-mpi/ompi/wiki/GitBestPractices
If you created that commit with "git pull", you can perform the rebase
equivalent by running "git pull --rebase". If this doesn't make sense, just
let me know and I can explain further and/or improve the docs around this.
Thanks,
-Dave
